The Elder Scrolls V: Skyrim

So i got this small bug where i transform into a werewolf, and when my time is up or i revert back to human for, i dont have any items equiped. Yes i know thats normal, but here is the weird part. Some items dont appear in my inventory, and those that do, if i click on them to equip them, they just disapear out of my inventory?? Only mod i have installed that affect my werewolf forms is TOL. So i reload my save just before the ritual, now the game appears to just freeze as soon as i want to drink blood
